SOLUTION: The grain culms are nipped by the feed chain 4 and the nipping rods 5 and conveyed in the threshing chamber 19. A turning fulcrum (a) is formed at the lower part of a chain-sliding member 29 for receiving and supporting the feed chain 4. Plural operating lever devices 6 for operating the turning of the feed chain to the locked state or the released state are installed in the upper part of the chain-sliding member 29, and the plural operation lever devices 6 are connected with connecting rods 39.
